Rosy, if it were me I would move, Joking aside it is a big job, you need to treat it as a long term project and do the work in sections you can manage in the spare time you may have remembering the good old British weather. Make sketches and a plan (a guide, plans can and do alter). Decide which small section you want to work on first, say a place to sit and contemplate the next move and where you can put down some nice pots of flowers to give you heart for the work ahead. The pond needs to be left as you will get Tadpoles then small frogs, one day you will look in the pond they will be gone, they always come back to the same pond the next year and very interesting to watch as well. So the pond renovation after wild life vanishes.
The lawn the biggest job and depends on funds available. You need remove all the grass, stack it upside down in a dark corner and leave for a couple of years you will have the best potting compost ever. It now needs to be dug over, this I would double dig adding in a good compost grit and washed sand as you go. Quite often there are local gardeners who would do this bit for you. For the lawn the best lawn would need around twelve to fifteen inches of topsoil added, once the pan has been broken up and drainage added six to eight inches would be OK, the lawn does need to be raised from what I see in the pictures. Now it is up to you seed or rolls, Garden Centres have reasonable grass rolls with a medium grass or order on line the type you want a soft does not take heavy wear Medium for Children and heavy duty for a football field in the garden dogs cats, keeping wild boar is not good for any grass.
To sow seed the top needs to be well raked all stone lumps of clay and any other bits taken off My last Lawn we riddled the soil added first. Rake it flat then do the gardeners shuffle, wear big flat boots and shuffle up and down the patch compacting it very slightly. Rake again with the back of the rake after checking levels, a long flat lath or plank moved along the patch will show high or low levels. Buy your seed from a good Garden centre read the packets it will tell you what it is best used for, light medium heavy use. then sow as the packet tells you adding a few extra hand fulls for the birds, WATER in and leave, I cut by hand for the first cut then the blades on the mower up for the next couple of cuts, my way is never cut below one inch long, scalping kills a lawn and you are not after a bowling green. Decide what you wish to do first and do it, trying to jump from job to job never works you end up with a complete building site, a bit at a time gives you something to look at and show you are getting there. Good Luck.
